Distinct isotopic and faunal changes occur across sapropels of late Pleistocene, early Pleistocene and latest Pliocene age, while smaller isotopic changes and more stable faunal assemblages are associated with the early and mid-late Pliocene sapropels. The large delta (super 18) O depletions and euryhaline fauna associated with latest Pliocene-Pleistocene sapropels supports a density stratification model with a low salinity surface layer. In contrast, early Pliocene and mid-late Pliocene sapropels appear to have been formed as the result of sluggish circulation and low oxygen contents in bottom waters, due to the stable, warm climatic conditions of that time period.--Modified journal abstract.completedStratigraphyanaerobic environmentbibliographyCenozoiccoresDeep Sea Drilling ProjectdistributionDSDP Site 374DSDP Site 376DSDP Site 378environmentForaminiferaInvertebrataisotopesLeg 42Amarine environmentmarine sedimentsMediterranean SeamicrofossilsNeogeneO-18/O-16organic compoundsorganic materialsoxygenpaleo-oceanographypaleoclimatologypaleoecologyplanktonic taxaPleistocenePlioceneProtistaQuaternarysapropelsedimentationsedimentsstable isotopesstratigraphyTertiaryurn:org.iodp:exp:42:site:374urnlargerWorkCitationstudyurn:org.iodp:exp:42urnlargerWorkCitationcampaignurn:org.iodp:exp:42:site:376urnlargerWorkCitationstudyurn:org.iodp:exp:42urnlargerWorkCitationcampaignurn:org.iodp:exp:42:site:378urnlargerWorkCitationstudyurn:org.iodp:exp:42urnlargerWorkCitationcampaignEnglishgeoscientificInformation25.000032.000034.500035.5000Baruch Inst.; Contrib.
